Erythrocyte Sedimentation Rate (ESR) whole blood Controls Levels 1 and 2 for manual and automated methods 8 x 9 ml ESR-Chex, Streck

ESR-Chex is a two-level haematology control used to monitor erythrocyte sedimentation rates. It provides superior sed-rate accuracy, reacting to physical factors such as benchtop vibration, temperature, and tube angle and alerts the technologist to possible problems that may affect the accuracy of patient results.

ESR-Chex is manufactured from human red blood cells and verifies the precision and accuracy of manual and automated methods. ESR-Chex is assayed for the most frequently used sedimentation rate tubes in conjunction with the Classical Westergren, Modified Westergren, and Wintrobe methods. Automated and modified procedures do not require removal of sodium citrate, and ESR-Chex is used in the same manner as a patient sample.
